The new lineup of Ruland beam couplings, including single beam (centre)
uland now offers MI-series single beam couplings, expanding its zero-backlash beam coupling line to include one, four,
and six beam styles. Single beam couplings are ideal for light- duty applications with low torque requirements such as encoders, tachometers, and small analytical devices.
The single beam couplings feature a single helical cut that allows for greater angular and axial misalignment than comparable multiple beam couplings, making them well suited for systems where precise alignment is difficult to achieve. In addition, their compact design and low bearing loads help protect sensitive system components, extending equipment life and improving overall reliability. MI-series couplings are available in clamp
or set screw styles with inch, metric, and inch-to-metric bore combinations ranging from 3/32 inch to 3/4 inch and 3mm to 20mm. They have pure metric outer diameters and lengths to better match international design standards. Hardware tests beyond DIN 912 12.9 standards
44
ensure the coupling reaches its maximum performance capabilities.
The addition of single beam couplings expands Ruland’s beam coupling size range, with outer diameters now up to 50mm. As a result, the expanded range gives designers more flexibility to select the right beam coupling style – single, four, or six beam – to meet the performance, misalignment, and space requirements of their application. Ruland single beam couplings are carefully manufactured from high-grade 7075 aluminium
bar stock sourced from North American mills in Ruland’s ISO 9001:2015 certified advanced manufacturing facility in Marlborough, Massachusetts. All Ruland couplings are RoHS3, REACH, and Conflict Minerals compliant. In the UK, Ruland products are available from Acorn Industrial Services.
